Kugadziriswa kwePVC inzira yakaoma kwazvo, iri nyore kugadzira kunaya, kushanduka kwemavara, kuderera kwepurasitiki uye mamwe matambudziko.Nekuti kunamatira kwePVC kunyungudika kune simbi senge screw, screw barrel uye kufa musoro kwakakomba panguva yekugadzira, zvinodikanwa kuwedzera mafuta ekudzikisa kunamatira kwePVC kunyunguduka kusimbi uye kuve nechokwadi chekugadzirisa kwePVC, inozivikanwa zvakare. semafuta ekunze.Parizvino, mafuta makuru ekunze anoshandiswa mukudzikamisa iparafini wax, Fischer Tropsch wax,wakisi ye polyethylene, oxidized polyethylene wakisi, nezvimwewo.
Fischer Tropsch wax ndeye yakatwasuka ketani yeparafini.Inowedzerwa muhuwandu hukuru muPVC chigadzirwa chekugadzirisa uye kugadzikana, iyo inononoka kugadzirwa kwePVC mune extruder uye inoderedza kushandiswa kwe stabilizer.Nekudaro, kune zvakare mhedzisiro senge isina kukwana plasticization, kunaya kwakakomba, uye kuderera kwezvinhu zvemuviri.Parizvino, vagadziri vazhinji vanowedzera oxidized polyethylene wakisi muformula yekuvandudza dhigirii rePVC kunyunguduka, kuitira kuderedza kunaya kwemvura, kuwedzera hupfumi hwekupedzisira uye kuvandudza hunhu hwezvigadzirwa.
Iyo oxidized polyethylene wakisi ichashandiswa semafuta ePVC kugadzira chigadzirwa kuderedza viscosity yezvinhu, kuvandudza kugona kwepurasitiki uye kuwedzera kupenya kwechigadzirwa.Iyo ine yakanaka wettability, dispersibility uye kuenderana mu masterbatch processing, uye kuita kwayo chigadzirwa kuri nani pane polyethylene wax.
Sainuo ope wax
(1) Yakakwira-density yakagadziridzwa wakisi, inogona kusimudzira plasticization, uye ine yakanaka post-thermal kugadzikana, inogona kupa zvigadzirwa zvakanaka plasticization uye kupenya, kuenderera kwenguva refu kugadzirwa kutenderera, mu masterbatch kuchawedzera kupararira uye kupenya, asi ine mhedzisiro pane oxidative induction nguva.
(2) MuPVC system, yakaderera density oxidized polyethylene wakisi inogona kuiswa plasticized mberi kwenguva, uye gare gare.
torque yakaderedzwa.Iyo ine yakanakisa mukati nekunze lubrication.Inogona kuvandudza kupararira kwe
colorant, ipa zvigadzirwa kupenya kwakanaka uye kunatsiridza kugadzirwa kwakanaka.

Mukugadzirwa kwePVC, ine yakanakisa adhesion kuramba uye inogona kuvandudza fluidity.Iyo yakanakisa yekuzora yekunze inogona kugadzirisa kuderedzwa kwezvigadzirwa zvePVC, kuderedza kubatana pakati pepolymer mamorekuru, kuvandudza kukweshera kupisa chizvarwa pakati pepurasitiki inonyunguduka uye inopisa simbi pamusoro pemidziyo yekugadzirisa, uye kugadzira yakatetepa yekuzora layer pane interface pakati pepurasitiki. kunyunguduka uye simbi.
(2) Zvimiro: yakanyungudutswa kabhoni kugovera, yakadzika mamolecular uremu kugovera, yakanyanya kuderera kupisa uremu kuderera, kwakanaka kwekutanga, kwepakati uye kunonoka kudzosa kuita, kunonoka kunonoka kwemafuta kugadzikana, hapana kutama, hapana kunaya, hapana kunhuwa, zvinoenderana neFDA zvinodiwa.
Qingdao Sainuo Chemical Co., Ltd.Isu tiri kugadzira PE wakisi, PP wax, OPE wax, EVA wax, PEMA, EBS, Zinc/Calcium Stearate….Zvigadzirwa zvedu zvakapfuura REACH, ROHS, PAHS, FDA yekuongorora.
Sainuo zorora wakavimbiswa wakisi, gamuchira kubvunza kwako!
